Abstract
The present disclosure relates to control systems, clock synchronization methods, controllers, node devices, and vehicles. In one example control system provided in this application, a primary controller directly sends a reference clock signal to at least one node device by using a ring network, so that the at least one node device can perform timing based on a frequency of the reference clock signal.
Claims20
A control system, wherein:
- the control system comprises a ring network, and the ring network comprises a primary controller and at least one node device;
- the primary controller is configured to:
- perform timing and execute a first task based on a frequency of a local clock signal of the primary controller;
- and
- send a reference clock signal to the at least one node device by using the ring network, wherein the reference clock signal is obtained by performing frequency division on the local clock signal of the primary controller;
- and
- the at least one node device is configured to perform timing and execute a second task based on a frequency of the reference clock signal.
A clock synchronization method, applied to a primary controller in a control system, wherein the control system comprises a ring network, the ring network comprises the primary controller and at least one node device, and the method comprises:
- performing timing and executing a first task based on a frequency of a local clock signal of the primary controller;
- and
- sending a reference clock signal to the at least one node device by using the ring network, wherein the reference clock signal is obtained by performing frequency division on the local clock signal of the primary controller, and the reference clock signal is used by the at least one node device to perform timing and execute a second task based on a frequency of the reference clock signal.
A vehicle, wherein the vehicle comprises a control system, the control system comprises a ring network, and the ring network comprises a primary controller and at least one node device;
- wherein the primary controller is configured to:
- perform timing and execute a first task based on a frequency of a local clock signal of the primary controller;
- and
- send a reference clock signal to the at least one node device by using the ring network, wherein the reference clock signal is obtained by performing frequency division on the local clock signal of the primary controller;
- and
- wherein the at least one node device is configured to perform timing and execute a second task based on a frequency of the reference clock signal.
